SOURCE: wont run...
Any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Get a fresh set of stock NGK spark plugs. Clean or replace the air filter. You seem to be pretty thorough in what you have done, but since plugs and filter weren't mentioned I had to ask.
Assuming you are getting air, gas and spark, and the timing is correct then it should run. Right? Not necessarily. Can the bike breathe? If pressure cant get out of the tailpipe the bike won't run. Mufflers can sometimes collapse internally. This restricts the flow of burned gasses. causing backpressure. If nothing goes out of the cylinder then nothing goes in.
Try removing the exhaust pipes. Now see if it will run. Get back to me because I would like to know what you find.

SOURCE: no spark
Hi and welcome to FixYa,
To my understanding, the problem is 'no spark' yet the engine cranks. Generally, to consider are:
Offhand, the CDI would be the main suspect. Since the CDI is sealed, it is not possible to do component level checks. The only way to check if the CDI is good is to check the external connections; if they are good and yet no spark, then the CDI is bad.
How to check the above:
Good luck and thank you for using FixYa.

Probably a gas delivery problem to the carbs. Check the lines and check for a filter in the line or at the carbs. Something is stopped up and it can't get enough gas to go any rpms.
